The significance for OD6 is not simply the registration itself. It is about ensuring the Company is appropriately positioned to engage with U.S. Government agencies and pursue applicable funding, contracting and strategic partnership opportunities as Quinn progresses. What makes this particularly relevant for OD6 is that fluorspar is not only recognised as a critical mineral by the United States, but is also specifically identified as a priority material by the Defense Logistics Agency under a currently open program focused on rebuilding domestic strategic-material supply chains. The DLA’s focus on refining, processing and beneficiation is also closely aligned with the work we are undertaking at Quinn through our ore sorting and comprehensive metallurgical testwork programs. Our immediate priority remains demonstrating the technical and economic potential of Quinn. At the same time, we are putting the corporate and government engagement framework in place so that, as the Project advances, OD6 is positioned to pursue appropriate U.S. Government funding and strategic partnership opportunities.. 2 OD6 Metals Limited (ASX: OD6) (“OD6” or “the Company”) is pleased to advise that it has completed registration with the United States Government’s System for Award Management (“SAM.gov”), establishing an important federal registration platform from which the Company can pursue applicable U.S. Government contracting, financial assistance and strategic critical-minerals opportunities. SAM.gov is the official U.S. Government system through which entities register to participate in applicable federal contracting and financial assistance programs. The registration represents another important step in OD6’s strategy to establish the Quinn Fluorspar Project in Nevada as a potential future domestic source of fluorspar to the United States. OD6’s registration is particularly timely given the increasing focus of the U.S. Government on securing domestic sources of critical and strategic minerals, including fluorspar. Fluorspar Recognised as a US Critical Mineral Fluorspar is included on the United States’ Final 2025 List of Critical Minerals, published by the U.S. Department of the Interior through the U.S. Geological Survey. Under U.S. legislation, critical minerals are those considered essential to the economic or national security of the United States, with supply chains vulnerable to disruption and which perform essential functions in manufacturing. The strategic importance of domestic fluorspar supply is further highlighted by the United States’ reliance on imported material. According to the USGS Mineral Commodity Summaries 2026, excluding sales from stockpiled material, the United States was 100% net import reliant for fluorspar in 2025, with significant U.S. fluorspar mine production not reported since 1995. The U.S. Defense Logistics Agency (“DLA”) Strategic Materials division also specifically recognises fluorspar as a strategic material. DLA describes: • metallurgical-grade fluorspar as typically containing 60–85% CaF₂ and being used principally in steel and cement production • acid-grade fluorspar as containing greater than 97% CaF₂ and being used in the manufacture of hydrogen fluoride , hydrofluoric acid and Aluminium fluoride. Fluorspar applications extending across metal processing, steel and iron production, semiconductor etching, electrical power distribution, pharmaceuticals and other advanced industrial applications. DLA Currently Prioritising Fluorspar Importantly for OD6, the Defense Logistics Agency Strategic Materials division currently lists fluorspar as a priority material under its open Broad Agency Announcement (“BAA”) for Basic Research and Qualification. The DLA states that the program responds to the need to restore and stabilise domestic strategic and critical materials supply chains affected by reduced domestic mining and refining capacity or insufficient domestic reserves. Fluorspar is specifically identified by DLA among the materials currently prioritised under the program. Areas of interest under the program include: • refining, processing and beneficiation • recycling, conservation and substitution • qualification of materials 3 The current DLA BAA is scheduled to remain open until 30 January 2029. The inclusion of fluorspar within this U.S. Government program provides a clear strategic backdrop to OD6’s development of the Quinn Fluorspar Project and, in particular, the Company’s current focus on ore sorting, beneficiation and metallurgical testwork. Position Quinn within the US Critical Minerals Strategy Quinn is located in Nevada, USA, and therefore provides OD6 with the opportunity to potentially contribute directly to the development of a secure domestic U.S. fluorspar supply chain. OD6 is systematically advancing Quinn through a number of parallel workstreams including: • geological mapping and sampling • advancement of exploration and drilling permitting • environmental and cultural baseline studies • ore sorting and beneficiation testwork • comprehensive metallurgical testwork • evaluation of potential future processing pathways capable of producing metallurgical-grade and/or acid- grade fluorspar products. Recent metallurgical sampling has been deliberately designed to evaluate both mineralisation and potential mining dilution, with representative high-grade, medium-grade and low- or non-mineralised material being incorporated into the current testwork programs. The Company’s ore sorting work and broader metallurgical program are intended to establish the ability to beneficiate Quinn mineralisation and determine the most appropriate processing pathway towards saleable fluorspar products. Potential US Government Funding Pathways The U.S. Government has increasingly deployed a range of funding and procurement mechanisms aimed at strengthening domestic critical-mineral supply chains. These include programs administered through the Department of Defense, Defense Logistics Agency and other federal agencies. The Defense Production Act (“DPA”) Title III and Industrial base programs has previously been used to fund the development and expansion of domestic critical-mineral mining, beneficiation, processing and refining projects. Department of Energy, Critical Minerals program OD6 intends to assess whether Quinn may be suitable for participation in relevant U.S. Government programs as the Project advances and the required technical, metallurgical and economic information becomes available. The completion of OD6’s SAM.gov registration provides the Company with an important administrative foundation from which to undertake that engagement. The Company will also continue to assess other potential U.S. Government financing pathways where appropriate, including programs supporting domestic manufacturing and secure critical-mineral supply chains. No application for funding has presently been approved and there can be no assurance that OD6 or the Quinn Fluorspar Project will receive funding under any U.S. Government program. 4 Quinns Fluorspar Project U.S Strategic Advantage The Quinn Fluorspar Project, located in Nevada, USA, provides OD6 with direct exposure to a strategically important critical mineral within the United States. The Project's key attributes include: • location in Nevada, USA, one of the world’s established mining jurisdictions • a historical fluorspar mining district containing multiple known fluorspar occurrences • OD6 has now consolidated 100% ownership of 226 mining claims covering ~1,890 hectares • +20 Fluorspar occurrences, supporting a future hub-and-spoke development strategy • exceptionally high-grade fluorspar mineralisation demonstrated through OD6’s recent exploration and sampling programs • Multiple high-priority drill targets defined from integrated geological mapping, fluorine geochemistry, structural interpretation and historical drilling • 8km fertile mineralised corridor confirmed with additional high-grade fluorine anomalies identified outside known deposits • Low impurity mineralisation supports potential production of premium Acidspar (>97% CaF₂) and Metspar products following beneficiation • Permitting program underway, including environmental baseline, archaeological studies and preparation of drilling and bulk sample approvals • Metallurgical testwork advancing with optical sorting and beneficiation studies to optimise premium product recoveries • Potential Gold Upside identified in soil sampling across Mammoth, Horseshoe and Dress Circle Together, these results reinforce OD6's view that Quinn has the potential to emerge as a strategically significant domestic source of high-grade fluorspar in a U.S. market that remains 100% net import reliant.
